如果我有一個通配符的完整路徑，我怎樣才能得到最舊的LastWriteTime的文件？

$fullpath = "myFolder:\foooBar*.txt" 
$theOldestFile = # What to write to get among the 
       #fooBar*.txt that has the max LastWriteTime?

這樣的：

$fullpath = "myFolder:\foooBar*.txt" 
$theOldestFile = dir $fullpath | sort lastwritetime | select -First 1
